Research Abstract |
Metal surface with hairline which put a scratch in a certain direction has different gloss feeling at different point of view. We have developed a method to evaluate gloss of the metal surface, taking into account the anisotropy in a short period of time extensively in lighting with a black and white pattern. The developed method evaluates gloss including the anisotropy by rotating the black and white stripe pattern. In addition, it was found that there are a certain relationship between the gloss and the surface roughness.
